I bought an xbox360 slim and it came with fsd 3 plus a 250gb internal, after installing about 28games there was no space left, i played for like one week and decided to get a 500gb internal. But now the problem is that when i installed the first game into the new hdd the game cant get executed right from the xbox360 games list i have to execute it manually from the file manager, yet the same game i have it on my usb and when i set the path to usb0 the game executes from the xbox360 games list on fsd without any problem. What is wrong with my hdd or is there something am not getting right? this is my first xbox 360 and i dont know what to do, anyone help please. Any ideas.
